Different demands for effectiveness will make the structure of the chair significantly different. For example, the structure of a foldable and non-foldable chair is different. ίο 15 20 A collapsible chair is commonly referred to as a folding chair, and usually uses the preset support in its chat rack to pivotally install two intersecting and hollow tubes. When framed, the support passes directly through the two tubes. The corresponding perforations opened above allow the two pipe fittings to be combined, and the combined state 'Although this pivot I coupling structure can have a folding function, the destructive perforation of the pipe fittings will affect the strength of the pipe fittings. Plus π In addition, when the foot frame of the chair is designed to be fixed in length, its structure will be significantly different from the structure in which the feet are stretched to 10% ifg. Take a tripod with a length of the telescopic reshaping force b as an example. 'The tripod design shown in the first picture, which has the first and second outer sleeves, the second hollow f 11, 12, and-is used to limit the position.之 V 型 弹 扣 片 13。 The V-shaped buckle sheet 13. The second hollow tube 12 has holes 12 located in different heights. The v-shaped elastic buckle 13 is contained in the first one. The inner hollow tube 12 has a body that protrudes outward through the first hollow body and can be selected. Insert one of the second hollow tubes 12-the latch 131 in the adjustment hole A, as long as the latch 131 is pressed in by hand to move it away from the entire circle hole 121 'the whole first hollow tube 11 and The V-shaped spring buckle piece 13 can be moved up and down relative to the second hollow tube 12, @ v 型 弹 扣 片 13 can be 5 捌, the new description (2) to another adjustment of the second hollow tube by itself When the locking pin ΐ3m is displaced in the hole 121, it will be snapped into the adjustment hole 121 again to lock the first, U, and 12 into position. Although this adjustment structure can achieve the effect of length adjustment, it is not only inconvenient to press the latch 131 of the V-shaped elastic buckle piece 13, but also during the operation of dust pressing, it may be deformed due to the use of time or the diameter of the latch 131 due to It is misaligned and cannot be reset, which causes the trouble that the first and second hollow tubes u and 12 cannot be locked and positioned. ° [New content] The purpose of this new model is to provide a folding chair that does not have perforations on the pipe fittings and has a very stable telescopic adjustment function when it is pivotally installed. Thus, the new folding chair includes: two left and right spaced tripod units, a seat frame assembled on the two tripod units, four adjusting mechanisms for controlling the extension length of the two tripods, and A seat cushion fixed to the seat frame. The female tripod unit includes an inner leg tube and an outer leg tube, and an inner pivot plate and an outer pivot plate which are welded upright at a position near the middle of the inner leg tube and the outer leg tube and are connected to each other in parallel. And a telescopic tube which is retractable and protrudes and is inserted into the upper end of one of the outer leg tubes, and the telescopic tube has a plurality of adjusting holes at different heights. The two adjusting mechanisms are respectively assembled on the bipod unit, and each adjusting mechanism includes a hollow fixed shell seat fixed to the outside of the foot tube outside the corresponding tripod unit, and a bolt inserted into the fixed shell seat. A set of 6 M245885 捌, a new type of description (3) an elastic part outside the pin and limited to the fixed shell seat, one of the outer ends of the pin penetrates out of the fixed shell seat, and the pin is subject to the elasticity The pieces push against and push their inner ends through the outer leg tube, and can be selectively inserted into one of the adjusting holes of the corresponding telescopic tube. The child frame is pivotally mounted on the top of the leg tube and the telescopic tube inside the bipod unit. [Embodiment] The description of the new model and other technical contents, features, and effects will be clearly understood in the detailed description of the preferred embodiment with reference to the drawings after repairing. 15 20 Referring to the first and second figures, the preferred embodiment of the new folding chair includes a left and right spaced tripod unit 2, a pivot rod 3 and 2 for connecting the tripod unit 2 together. A linkage bar 4 between the bipod unit S 2, a seat frame 5 assembled on the bipod unit 2, and an adjusting mechanism 6 for controlling the telescopic length of the local position of the bipod unit 2 And a seat cushion fixed on the seat back frame 5. As shown in the fourth figure, each tripod unit 2 includes an inner leg tube 21 which can be foldably intersected and pivoted. 〃 Outer foot officer 22, which is welded upright to the inner leg tube 21 and the outer leg tube, respectively. 22 folds, an inner pivot plate 23 and an outer pivot plate 24 corresponding to each other at the middle and parallel to each other, are inserted into an upper end of the outer leg tube 22 with a π and a retractable and protruding upward 1 A ^ & 25. The telescopic tube 25 has most of the positive holes 251 facing outwards and at different heights, which can cooperate with the control of the corresponding adjustment mechanism 6, and your Shigu ^ telescopically moves up and down relative to the outer leg tube 22 to the south degree. Positioning it, the relevant structure and operation of the adjustment mechanism 6 on the woman's side, the new type description (4), the operation will be described in detail below. «Hydro Pivot 3 extends left and right with its opposite ends passing through the inner and outer pivot plates 23 and 24 of the Λ-foot unit 2 respectively, and the inner and outer pivot plates 24 are pivoted together. The inner leg and the outer leg tube of each tripod unit 2 are pivoted relative to each other with the pivoting part of the pivot rod 3 as an axis. Moreover, the central part of the pivot lever 3 has a downwardly curved shape with respect to its two opposite ends. Since the inner and outer leg pipes 21 and 22 of each tripod unit 2 are respectively welded by the inner and outer pivot plates 23 and 24 which are fixed by the cymbal 3 and pivoted by 10, there is no need to include 2. The walls of the outer leg tubes 21 and 22 are provided with perforations that destroy 10, which will not affect the strength of the inner and outer leg tubes 21 and 22. The two interlocking crossbars 4 are respectively connected between the bottom end of the inner leg tube 21 and the bottom leg of the outer leg tube 22 of the bipod unit 2, so that the two inner legs & 21 of the bipod unit 2 are opposite to When the two outer leg tubes 22 are pivoted, the pivots can be synchronized with each other. 15 The seat frame 5 is roughly ring-shaped, and has a pivot seat 53 welded to its bottom surface at four intervals. The pivot bases 53 are respectively used to be pivotally mounted on the two feet, the top of the inner leg tube 21 and the telescopic tube 25 in the unit 2. Each pivot base 53 is in the shape of an inverted U-shaped plate, and its two ends are Fitting and inserting a branch body 54 is pivotally mounted corresponding to the top end of the corresponding inner leg tube 21 or telescopic tube 25. 20 — The second adjustment mechanism 6 is assembled on the outer side of the near end of the leg tube 22 outside the bipod unit 2. As can be seen from the fifth figure, each adjustment mechanism 6 includes-fixed to the corresponding outer leg tube 22 The upper hollow fixed shell seat & a latch 62 inserted into the fixed shell seat 61, an elastic member which is fitted outside the pin a and is limited to the fixed shell seat 61, and a fixed 8 M245885新型, new type description (5) = sheath of the outer part of the Γ lock 62 ". The fixed shell base 61 is roughly cylindrical. The latch 62 is horizontally and horizontally arranged, and has a collision ring extending from the periphery to the radial expansion. , The pin 62 and the outer end of the fixed shell seat 61 with the end 621, and can be pulled by hand: 'And the elastic member 63 is fitted on the outside of the pin 62, outside the outer leg 22, and the lock 62- The inner end seems to pass through the outer foot = 2 of the telescopic tube 25 corresponding to the miscellaneous person-inside the adjustment hole. Ίο 15 »HAI Zun sleeve 64 疋 solid sleeve covering the plug & outer end 6 can be convenient People hold hands. 丨 And the whole hole is softened. When the bolt 62 is pulled out, the inner end portion 622 is moved away from the adjustment hole 25, and the entire telescope f 25 can be removed. For the outer leg tube 22 to lift and lower the position μ, it is necessary to release the plug 62 'to reset the plug lock 62 and choose to insert another adjustment hole 251 by the pushing force of the elastic member 63. Then, the outer leg f 22 and Shenxian 25 is positioned for inserting, so it is very convenient to fall, and because the latch 62 is located outside the outer leg tube 22 'and only penetrates the telescopic tube 25 with its inner end portion 622 during operation, the overall latch M does not The situation that it will fall into the telescopic tube 25 and cannot be adjusted by operation occurs. Compared with the operation mode of the lock lock 3 of the v-shaped elastic piece 13 in the first figure of the financial description, the telescopic adjustment function of this embodiment is indeed very Stable. When the telescoping tube 25 of the Tianyihai wooden single χ 2 is lifted and displaced at the same time, the seat frame 5 is pivotally mounted on the top of the two telescoping tubes 25, and will be linked to rise and fall relative to the top of the two inner tube 21 The displacement has the effect of changing the inclination angle of the entire sitting frame 5. Zheng 20 M245885 捌, new type description (6) The cushion 7 is made from the first-reed ... The two pictures can be seen ’is fixed on the delta frame 3 near its periphery. The seat holder ^... ^ The pad 7 can be sewn from a soft material such as canvas, and sewn into a central slightly # ^ ^ Tianluo lower depression extending into a disc-shaped body, and the seat 5 10 15 7 central in the lower depression The depth is roughly the center of the ship and the lower arc. 1 — When the overall folding chair is to be folded, in a state where the outer leg 22 of the bipod single U stands against the ground, the lower end of the two inner leg M can be pivoted upward to parallel and reach. Until the two outer leg tubes 22 and the two telescopic tubes _ side eight at the same time 4 sitting frame 5 will also be linked and merged at the front of the outer leg tube 22, and folded into a flat overlapping as shown in the sixth figure shape. To sum up, the design of the new folding chair can not be welded by the inner and outer pivot plates 3 and 24 of each foot unit 2 and outer leg tubes 21 and 22, and the pivot pin 3 teeth insert It is pivoted so as not to affect the strength of the inner and outer leg tubes 21 and 22, and during the operation of these adjustment mechanisms 6, it is used to insert: the leg tube 22 and the pin 62 of the telescopic tube, and there will be no overall fall Telescopic & 25 can not be adjusted in operation, making the telescopic adjustment function very stable, so it can indeed achieve the purpose of this new model. The above is only the preferred embodiment of the new model. When the scope of implementation of the new model cannot be limited in this way, that is, the simple equivalent changes and modifications made according to the scope of the patent application of the new model and the content of the new specification, All should still fall within the scope of this new patent.
